Inline equations

tags: equations mathjax

Description/Summary

Content

• Inline equations are wrapped between \( and \).

  • $ wrapping also works, but it is not preferred as it comes with restrictions like “there should be no whitespace between the equation and the $ delimiters”.

    So $ a=b $ will not work (it will look like: $ a=b $), but $a=b$ will work (it will look like: \(a=b\)).

    On the other hand, both \(a=b\) (it will look like: \(a=b\)) and \( a=b \) (it will look like: \( a=b \)) will work.

• One-per-line equations are wrapped between \[ and \] or $$ delimiters.

For example, below in Org:

LaTeX formatted equation: \( E = -J \sum_{i=1}^N s_i s_{i+1} \)

will look like this in Hugo rendered HTML:

LaTeX formatted equation: \( E = -J \sum_{i=1}^N s_i s_{i+1 }\)

(Don’t see this in Markdown, see what it looks after Hugo has processed it.)

Here’s another example, taken from (org) LaTeX fragments.

Below in Org:

If $a^2=b$ and \( b=2 \), then the solution must be either
$$ a=+\sqrt{2} $$ or \[ a=-\sqrt{2} \]

renders to:

If \(a^2=b\) and \( b=2 \), then the solution must be either \[ a=+\sqrt{2} \] or \[ a=-\sqrt{2} \]

(Note that the last two equations show up on their own lines.)
